The 1.4.4 version of the plugin is not compatible with moodle 3.9.
The functions upgrade_fix_config_auth_plugin_names() and upgrade_fix_config_auth_plugin_defaults() called in the file db/upgrade.php have been removed in version 3.9 of moodle (see https://github.com/moodle/moodle/blob/master/auth/upgrade.txt).
